2. Description of the Prior Art

Typical water flushing devices for the floor toilets comprise a housingdisposed on the floor and coupled to a water reservoir for receiving thewater from the water reservoir, the housing including an outlet portdirected or coupled to the floor toilet bowl, a membrane disposed in thehousing, a valve device disposed in the housing for controlling thewater to flow through the membrane and to flow from the housing to thefloor toilet bowl, and an actuating handle or lever coupled to the valvedevice for actuating or operating the valve device to control the waterto flow from the housing to the floor toilet bowl.

The valve device may be actuated or operated by the actuating handle orlever in order to open the water flowing passage in the housing whenrequired, and may be actuated or operated by the water flowing into thehousing. One or more gaskets are engaged into or through the membraneand each include a bore for controlling the water flowing through themembrane.
